DRAFT-EVENER.

Specification of Letters Patent.

Patented July 24, 1906.

Application filed September 11, 1905. Serial No. 277,931-

To aZZ whom it may concern.-

Beit known that I, JOSEPH W. GAMBLE, a

I citizen of the United States, residing at Carpentersville, in the county of Kane and State of Illinois, have invented certain new and useful Im rovements in Draft-Eveners, of which the ollowing is a specification.

. My invention re ates to improvements in draft eveners or equalizers, and has for its object the production of an evener that will be ofsimple construction and yet capable of withstanding the hardest usage.

A further object is the production of an evener that will give a positive result by the use of the fewest parts and one that cannot be thrown out of adjustment by the movement of the horses or the implement.

A further object is the production of an evener that may be used on either side of the tongue by a simple adjustment of the parts thereof.

7 These and such other objects as may hereinafter appear are attained by my device, embodiments of which are illustrated in the accompanying drawings, in which- Figure 1 represents a plan view of my improvement applied to a three-horse evener. Fig. 2 is a rear elevation of Fig. 1.

i a sectional view on the line 3 3 of Fig. 1 looking in the direction indicated by the arrows. Fig. 4 is a plan view of my evener-castings attached to a tongue. Fig. 5 is an end elevation of Fig. 4. Fig. 6 is a plan view of a modified form of my invention. plan view of Fig. 6 ,sho wing the arts reversed. Fig. 8 is a sectionalview on t e lines 8 8 of Fig. 7 looking in the direction indicated by the arrows, and Fig. 9 is a sectional view on the line 9 9 of Fig. 5 looking in the direction indicated by the arrows.

Like letters of reference indicate like parts in the several figures of the drawings.

' Referring to the drawin s,A represents the tongue of an agricultura implement, Ba bracket-bar bolted thereon, O a brace-bar pivotally secured to the bracket-bar at b, and pivotally secured to this brace-bar at c is a doubletree D. At the ends of the doubletree D and at the outer end of the brace-bar O are swingletrees EE E.

Mounted on the tongue A, back of the bracket-bar B, is a bracket F, rigidly secured to the tongue at a a. [Extending upwardly from the face of this bracket F are bosses G H surrounding bolt-holes. An evener-lever Fig. 7 is a- I, having a long arm '5 and a short arm '11, is pivoted on the boss G. The lever I is also provided with stop-shoulders K k, adapted to engage the boss H, which preferably extends upwardly on a level with a low boss L 'on the upper face of the lever and surrounding the boss G. There is also a boss M on the under side of the lever I, mounted on the boss G and serving to su port the lever I above the face of the brac ct F and permit a free movement thereof on the pivot or boss G.

- A connecting-brace V is rigidly secured to the under side of the bracket F and to the under side of the tongue A in order to give proper rigidity to the bracket, and a connectingbrace V is rigidly secured to the bracket-bar and the bottom of the tongue in order to give proper rigidity to the structure. Tie-rods N O pivotall connect the arms, respectively, of the lever lwith the brace-bar O and donbletree D, respectively. A strap P, connecting the tops of the bosses L H, is held in place by a nut Q on the bolt J, which extends through the boss G, and by a nut R on abolt which extends through the bolt-hole in the boss H and serves also to confine the lever I to its seat.

Fig. 3 is Referring to Figs. 6, 7, and 8, showing a modification of my invention, the bracket F is provided on each face with a series of bosses or pins f f f and on this bracket is seated a plate S, aving holes therein re istering with the bosses or pins on the brac lket F. On the upper face of this plate S are bosses or lugs M H, having bolt-holes T T through their centers registering with the corresponding holes in the bracket F. With this modified device the lever I may be pivotally mounted upon the lug M, the lug H serving as a stop to engage the shoulders K 7c on the lever I. By reversing the bracket F and removing the plate S from one side of the bracket and placing it upon the other, as shown in Figs. 6 and 7, the device may be quickly and effectively reversed, so that the bracket F will extend from the right or from the left hand side of the tongue A, as may be desired.

The initial draft exerted by the horses attached to the doubletree D will be transmitted from the pivot-bolt 0 through the rod O to the long arm i of the lever I and will be taken up by the bolt J on the bracket F. At the same time the draft exerted by the single horse attached to the brace-bar C will be transmitted through the rod N to the short arm 4/ of the lever I, and since the brace-bar O is pivoted at b to-the bracket-bar B- it will be seen that'the arms of the brace-bar G and of the lever I are arranged in counter relation to each other, so that the longitudinal draft as between the single horse attached to the brace-bar C and the two horses attached to the doubletree D will be equalized. At

the same time the bracket-bar B, pivoted to the tongue A and to the brace-bar C on that side of the tongue opposite to the bracket,
